This invention relates to a metal carrier such as is used forYtransporting fiat metal bars, tubes, rods and the like about a mill, asfor example from rolling or drawing machines to annealing furnaces 'orany other-v they are lowered by craneonto sheet steelY pans which arepulled intovand through the annealing furnaces,'the pans, carriers andmetal being equally subjected to the heat in the furnace. After leavingthe furnace the hot metal bars,'tubes, rods and the like, with thecarriers are lifted from the pan by crane and immersed in thecoolingtankand then returned'to the rolling or drawing machine.

It is, therefore, an obj ect of this invention to provide an improvedconstructionv of carrier which will have the requisite strength Y andrigidity so thatthey will not crush or deform under heavy loads whenhot.

It is also an object of the invention to provide a carrier which isofsuflicient width to stand alone and facilitate loading atthe machine,and of such weight that they may be easily positioned by hand.`

Itis another object of the invention to provide an improved constructionof carrier which will have great strength and stiffness in proportion tothe amount of metal in and, therefore, the weight of the carrier.

With the foregoing and other objects in view, the invention consists incertain novel features of construction, combinations and arrangements ofparts as will be more fully disclosed in connection with theaccompanying drawing. d y

In this drawing Fig. 1 is a sideelevation of a carrier involvingk myimproved construction showing how it is used for carrying metal tubes,bars or the like. Y y

Fig. 2 is an end view thereof.

Fig. 6 is ya transverse section of the baseportion of a completed carrier. l l Fig. 7 is a transverse section of ametal plate which may be used in place of the pipe as the enclosingcasing, and y f Fig is a transverse section of the base portion of` acompleted carrier applying the member of Fig. y v

As indicated above, these carriers are intended to be used in pairsfortransporting metalv bars, tubes, rods or the like from the `rollingor drawingy machines, and'therefore,

must be capable of withstanding rough usage and must have the requisitestrength to carry relatively heavy loads even When hot. The carrier atpresent in common use comprises a flat or rectangular strip of metalbent to substantially U-shape, and is the best constructionhithertodevised, but it is very far from satisfactory because of its liabilityto bend and to break Aafter repeated straightening.

The construction shown in Figs. 1 to 6 comprises ametal rod 10 bent intoan elongated loop,'the first shape being indicated by the'V together',although it isnot absolutely necesf, sary that theyy be secured togetherand thisy joint may be located at other positions in the loop. Thenextfoperation in forming the carrier is to take a standard or otherpipe 13 as shown in Fig. 4 of the desired length and flat-ten it tosubstantially the shape lshown in Fig. 5.Y ,This flattened pipe is thenslipped over the elongated loop formed by the rod 10 with the spacedside bars 14 thereof in substantially'the position'shown in Fig. 5 andwith both ends of the loop indicated in dot and dash lines 11 projectingfrom the opposite ends of the enclosingcasing 13 as shown in Fig. 3.-y

draws the casing tightly about the bars 14 making a rigid construction,and these compressed portions 18 extend suiiiciently between the bars 14to effectively and rigidly hold them in the proper spaced relation. Theprojecting end portions are then heated and compressed somewhatlongitudinally so as to spread the loop somewhat as shown in dot-tedlines 15 of Fig. 3 at their free ends. These looped ends are then bentupwardly to a position'` indicated at 16,in Fig.l 1 forming uprightlooped ends to receive hooks 17 from a suitable crane or other carryingdevice.

` It will be evidenty from this construction that the base portionbetween the upright loop portions 16 is retained at the proper width sothat the carrier will readily stand along on the floor at the rolling ordrawing machines torpermit easy loading, and also the enclosing casingmember and side bars 14 Cooperate with each other to provide a centralor basey portion which is very strong and rigidV and .willl carry heavyloads of bars, rods, tubes or the like, a portion of which is indicatedat 9, without bending or deforming even. when hot.

plateor strip is used. After the rod has v2O in Fig. 8. This producessubstantially other `carrier construction heretofore devised,

' ation.

Figs. 7 and 8 show a slightly different construction of theenclosingcasing member for the central or base portion. In this forminstead ofusing afcontinuous pipe, a metal been bent into the elongatedloop, the opposite end portions spread somewhat as indicated at in Fig.3 and then bent upwardly A to the position 16as shown in Fig. 1, theplate 19 isformed to substantially the shape shown in Fig. 7 and is thenwrapped around the side` bars 14, of theecentral or base portion asindicated in Fig. 8, and then, the abutting edges of the plate arewelded as indicated at the same structure as shown in Figs. 1 to 6. Ifpreferred, the plate 19 may be wrapped around and placed in position onthe side bars vof the loop before the end portions are widened or bentto the upright position.v

It has been found that the above construction providesl a carrier whichis much stronger and less likely to be deformed or bent out of shapeunder heavy loads than any and particularly is this true when thecarrier 1s heated, as it must be when passed through the annealingfurnace with the rods, bars orV l tubes tobe annealed. rier sulicientlylight in weight to be prop-` It also provides a carerly positioned by`hand at` the machines where they are to be loaded, and the basevportions are of sufficient width so that 'they` will readily stand aloneduring the loading oper- They are also much stronger and much .morerigid in proportion to the metal used than is the old type of carrier.

Having thusset forth the nature of my ini Ventron, what I claim is `andan enclosing` member embracing the base portion and depressed somewhatbetween the sides of the loop to retain them in spaced relation.

A metal carrier comprising a metal bar in the form of an elongatedloop having spaced side members, the opposite end portions beingextendedV upwardly to form upright looped ends and a cent-ral baseportion connecting them, and an enclosingr member embracing the twosides of the base portion and depressed somewhat between them to retainthem in spaced relation. g
